Title
(EN) LED LIGHT BULB
(FR) AMPOULE DE LUMIÈRE À DIODES ÉLECTROLUMINESCENTES
(ZH) LED灯泡
Abstract
(EN)
An LED light bulb (2) comprising a light bulb body (21), a light head (22), a heat sink (23), an LED light panel, and a translucent cover (24). The light head (22) is fixed on the upper part of the light bulb body (21). The LED light panel is provided with several LED lights. The translucent cover (24) covers the LED light panel. The LED light panel is arranged on one side of the lower part of the light bulb body (21); the heat sink (23) is arranged on the other side of the lower part of the light bulb body (21); while the LED light panel and the heat sink (23) are arranged in parallel at the lower part of the light bulb body (21). The heat sink of the LED light bulb is provided with a large exposed area for increased rate of heat dissipation to extend the service life of the LED light bulb and provides same with expanded range of illumination to increase use efficiency thereof.

L'invention porte sur une ampoule de lumière à diodes électroluminescentes (2), laquelle ampoule comprend un corps d'ampoule de lumière (21), une tête de lumière (22), un dissipateur de chaleur (23), un panneau d'éclairage à diodes électroluminescentes et un capot translucide (24). La tête de lumière (22) est fixée sur la partie supérieure du corps d'ampoule de lumière (21). Le panneau de lumière à diodes électroluminescentes comporte plusieurs lumières à diodes électroluminescentes. Le capot translucide (24) recouvre le panneau de lumière à diodes électroluminescentes. Le panneau de lumière à diodes électroluminescentes est disposé sur un côté de la partie inférieure du corps d'ampoule de lumière (21); le dissipateur de chaleur (23) est disposé sur l'autre côté de la partie inférieure du corps d'ampoule de lumière (21); tandis que le panneau de lumière à diodes électroluminescentes et le dissipateur de chaleur (23) sont disposés parallèlement à la partie inférieure du corps d'ampoule de lumière (21). Le dissipateur de chaleur de l'ampoule de lumière à diodes électroluminescentes comporte une grande surface exposée pour un taux accru de dissipation de chaleur, de façon à prolonger la durée de vie de l'ampoule de lumière à diodes électroluminescentes, et confère à ladite ampoule une plage d'éclairage étendue, de façon à accroître l'efficacité d'utilisation de celle-ci.
